Hi Flossie
When my mum was out with me she felt she had to explain to people that I was 25 weeks pregnant. Otherwise than that people wouldn't have noticed. Then they made comments about how small you are and carry on a bit. Everyone becomes an expert.
You are how you are. My belly has since popped out (I'm now 36 weeks) but even so, I still don't think people really know that I'm due very soon. Which is fine, I don't really care what other people think. The baby is extremely healthy, as am I and in the optimal position for birth apparently - that's what the OB says and he is the only one I am listening to. Old wives tales don't cut it, in reality.
I've also suffered from cramps all the way through at the very bottom of my abdomen. Mostly at night and when I turn over in bed. I was worried to start off with but they have continued the whole time and baby and I are still here. The OB wasn't worried either.
